So the last night of my placebo week, my bf and I had unprotected sex. The next morning, (today) I realized I'd forgotten to pick up my new pack from the pharmacy. I take my pill everyday between 1 and 3:00 after class/work. I know that's not perfect but I know I can get back on schedule in the future. Anyway, I picked up my new pack today and took it around five, so approximately three hours later than usual. So prior to this point, I haven't felt taken my pills perfectly but I've taken them almost at appx. the same time everyday. Could I get pregnant? Should I get Plan B? I'm on a combination pill
